STEAM-TURBINE..

SPECIFICATION forming part of Letters Patent No. 789,244, dated May 9, 1905.

Application filed October 1, 1902. Renewed October 26, 1904. Serial No. 230,030.

To all whom it may concern:

Be it known that I, HANS THORWEYERJL subject of the King of Prussia, German Emperor, residing at Halle, in the Kingdom of Prussia, Germany,have invented acertain new and useful Improvement in Elastic-Fluid Turbines, of which the following is a specification.

My present invention relates to a steam-turbine; and it consists in so constructing and arranging the parts that the exit-openings of the cells are closed when steam is admitted, while their inlet-openings are closed after the admission. The exit-openings of the cells are so narrowed that the high-pressure steam contained in the cells after the impingement is distributed through several of the guide-cells.

In the accompanying drawings, Figure 1 is vertical section through the turbine, and Fig. 2 an elevation showing several of the cells and steam-orifices in section.

The turbine consists of the main parts casing A and the moving-wheel B, firmly connected with the shaft C.

Steam is conducted to the turbine through the pipes D, which open out into the steamchambers E. From the chambers E the steam passes through the orifices c into the inner cell series a of the wheel B. by the pieces f of the guide device 0, connected to the casing, when steam is being admitted into the same,so that said cells will only receive steam until the pressure therein is equal to that in the steam-chamber E. The steam therefore cannot escape from the first series of moving cells into the guide-cells, as in turbines of known construction, but must transmit its full power to the wheel. After the cells thus filled have passed the steam-inlet orifices their outlet-orifices are opened and the inlet-orifices closed by the wall of the steam-chamber E. The inclosed high-pres sure steam then enters the cells of the guide devices 0, reacting thereon owing to its expansion. As the exit-orifices of the cells are narrow and the change from cell to cell very quick, the steam from each cell of the first series will enter several cells of the guide device 0. In this manner the velocity of the steam is increased, so that its power can be better utilized.

These cells are closed In consequence of the continuous exhaust of the freshly-chargedcells of the wheel B into the cells of the guide devices 0 a uniform pressure will be present in the latter cells, and this pressure will act on the second series I) of cells of the wheel B in the same manner as the steam issuing into the cells of the first series from the steam-orifices 0, except for the difference that the pressure of the steam owing to its distribution over several channels will be decreased. A larger area of exhaust is, however, provided. The pressure remaining in the cells of the second series I) is utilized by reacting on the blades cl. From the exhaust-chamber F the steam escapes through the opening G. The breadth of the cells and the orifices is to be seen by the lines dotted through the parts 0 a b c, Fig. 1. For high pressures the number of the cell series must be increased.

Over other constructions my improved turbine possesses the advantages of consuming less steam, better utilizing the steam at low pressures, and full expansion of the steam independent of the steam-orifices. The turbine can also be operated by compressed air or gas.

In an elastic-fluid turbine, a turbine disk wheel provided adjacent to the periphery with annular flanges extending outward parallel with the axis, a plurality of fluid passages or cells formed in and through the flanges, passages for directing the pressure fluid to the inner opening of the fluid passages or cells of the inner flanges of the wheel at a plurality of points, guide-cells carried by the casing lying in the annular space between the flanges of the wheel, and vanes carried by the casing arranged exterior to the wheel, the construction being such that the peripheral distance between any two of the pressure-fluid-directing passages is such that a greater number of the fluid-passages of the wheel will be cut off from the fluid-pressure supply, than are in communication therewith, and that one-half of the fluid passages or cells of the outer flange 5 of the wheel will always be cut ofi from the fluid-pressure supply, in. series of three, the pressure-fluid passages being less in number than the fluid passages or cells of the flanges of the wheel, and the peripheral distance-be- IO tween the outlets of any two of the fluid-pressure passages being not less than the distance between any three of the abutting inlets of the fluid passages or cells of the wheel-flanges.

In witness whereof I have hereunto set my hand in presenceof two witnesses.
